    Cool AK youtube videos

    Why we wear safety glass, effective ones.

    AR-10 R+2 Gas Tube

    Posted final stuff over on Dracomeister's thread. The AP BCG fixed the 6mm issue with new WOA gas tube, the KAC- DD and ADK found functional homes in the 6.5CMs so all is well thanks. So compatibility is where you find it.

    New 20" barrel, now it short strokes

    Standardization and compatibility is continuing problem? I have a mutant 24” 6mm Creedmoor R+2 rifle. Original position of gas tube was like that in Dracomeister’s picture. First 14 rounds thru barrel became eventful. Initial three used ADK Defense BCG, seemed to function, switched to KAK BC with Davidson Defense NIB Bolt which was used to set barrel extension. Rifle failed to eject fired casing on last round of a group. Dropped it in receiver with bolt in hold back cleared by hand. During next group it did it again but unnoticed which resulted in casing jam pushing gas tube further forward as shown. After some zealous advice by members here I purchased a custom length proper gas tube from WOA, third picture. With new gas tube installed, ADK BCG would not fit in receiver enough to close. KAK-DD did fit but operated very tight. Both of these BCGs work in 6.5CM shown in fourth picture. So I purchased an Aero Precision BCG in hopes it would properly match receiver with new WOA precise located gas tube. This thread has a wealth of information exploring issues of a non-standard design. Seeing the side by side picture here I examined mine the same way. ADK gas key appears longer. Is it long enough to prevent receiver closing with new gas tube? So I thought I’d organize the data in this thread to see where my stuff stands. First I organized dimensions being collected and then built a matrix of data. Yes, ADK gas key is longer by 0.02, slot is deeper by about 0.05, and bolt closes smaller. So what does it mean? What is keeping ADK BCG from seating properly in order to close 6CM AP M5E1 receiver? AP BCG is fully functional in AP M5 6.5CM and now M5E1 6mm receivers. ADK is working in AP M5 6.5CM, and the KAK-DD in the M5E1 6.5mm. So all is well for now. Why do they work in this one versus that one I don’t know but if it is not broke don’t fix it.

    The ADK length and long gas tube are most likely this BCG will not fit with the new WOA gas tube Aero Precision BCG arrives tomorrow.

    This is the matrix I be populating if you all think it would be useful. Didn't have any time this weekend but did this morning>

    Great stuff thanks for the link. I'll try to compile it all in a spread sheet along with my 3 sources added (KAK, ADK, AP with natural bolts and Davidson Defense). Think I have to take picture of spreadsheet when done in order to display it here, is that correct? Plus the picture of the gas tube position in the thread clip, is exactly where mine was before the smash jam. John at WOA reminded me that the AR-15 gas tubes are not the same as an some LR-308 or AR-10. The tube I installed was their off the shelf AR-15 R+2. Since my mutant barrel needed the extra 3/8" he said was common for an AR-10 spec.

    PS your tinfoil hat will be ineffective. It needs to be conically corrugated to accommodate wider frequency spectrum.

    This might be a form of social media but it is for technical information IMHO. It is not facebook, twitter, etc., Also the questions I used as an example are like those you have for account security with banks, credit cards, as civilian examples OPM is Office of Personnel Management. Snowden: so what, Its progressives that bother me more, like to give them an all-expense paid Caribbean vacation. (progressives are not Flow from the insurance company they are Communists with patience) Progressivism has had three definitions over time, Teddy Roosevelt, Bob Lafollette, and now Saul Alinsky types. This later group is the one I am referring to. Hope I answered all your questions Now can we get back to gun technical stuff. I am still trying to understand the variations of BCGs with respect to the various LR308 receivers. Of course there is no standard for LR308 stuff, right?. It appears from my collection of BCGs that there is issues with BCG carrier length, gas key tube length and placement and the stroke of the extended bolt. No two are a like. So I bought an AP BCG to go with my AP receivers in hopes that they are compatible within the company's designs.

    OK simply put PLA-MI https://en.wikipedia.org/wiki/People's_Liberation_Army#Military_intelligence GRU https://en.wikipedia.org/wiki/Main_Intelligence_Directorate And their hacking of the OPM files is public record. I'd look it up for you but this should sufice

    Chinese and Russian military intelligence agencies. GRU is like our DIA, KGB like CIA etc. Well I haven't responded because I was in process of moving to my alternated location and didn't want to start a custom order with WOA until I sure I was going to be able to receive it. So last Tuesday I got with Jim WOA and made the order. He called back that afternoon to confirm a measurement and I received the new gas tube Friday morning. That is really fast for custom order and I now appreciate why Jim wants to keep it simple and quick. At $40 delivered you can't waste time and make any money well very good for them. The attachment shows the new location perfectly centered on the cam nut cutout in the upper receiver. Beautiful. Only my crapola BCGs don't work so smoothly. The ADK version shown in my other extractor thread would not close receivers so it is out. The KAK-DD BCG did close but fits really tight and you almost have to hammer the charging handle to get it to release. I fire tested this one, first one round smoke test follow by five round high speed. Once you get then thing in hold back it works fine. Question how much gap should be visible between the BCG front edge and the ejector opening in the receiver if any? Why is the bolt release so hard, the bolt was fit to the barrel and extension during barrel assemble?

    Did somebody see a slack convoy go by, NOT a chance on this site. This is almost fun.

    Here is a clue, I only do e -mail no social media. If you want to know more ask the FLA or the GRU they stole all out security records and background investigations. They know my first dog's name, my 1st grade teacher's name, and the address where my mother met my father and anything else in there. That's my combine 50 year pin for service in DoD.

    Thanks. Yes it is hard, tried and old. When I talked to WOA they didn't seem to volunteer to make a truly custom tube so when you all pulled out the band wagon I was slow to recognize my close mindedness as to what WOA would do. I'll try again in the morning, thanks.

    Very correct I have been e-mailing them and conversing with a John Holliger. so I need to call and ask about a truly custom, one of kind gas tube. Not necessarily the ones they call custom.
